Hamas' internal security service confirmed it had arrested several other jihadists

Hamas police detained a suspected jihadist leader in Gaza on Saturday, a security source said, the latest in a series of arrests of those accused of Islamic State group ideology.

"This morning, security forces arrested Nour Issa, 27, who is a leader of the deviant thought movement and is from Bureij Camp in central Gaza, along with others," the source said, using a phrase Hamas officials routinely use to refer to jihadists, including IS.

The internal security service confirmed on its Facebook page that it had made a number of arrests.

"One of the leaders of the deviant thought has been arrested along with others," it said, without giving a name. Hamas has arrested a number of Salafist and IS-linked figures in recent years.
